Covering some 138 hectares, the south Caspian Sea retreat is a tourist destination for domestic holidaymakers, yet it draws nature lovers and birdwatchers.

The region embraces a variety of freshwater lakes, wetlands, and lagoons, many of which play host to migratory pelicans, flamingos, ducks, swans, coots amongst other species.
